A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
3D rendering of biotinylated antibody, an engineered protein designed to bind to specific molecules. Biotin allows researchers to easily track and manipulate these antibodies.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
29 October Republic Day of Türkiye text on a red shiny sphere with a partial Turkish flag on white background. Easy to crop for all your print sizes and social media needs.
CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background

Medical Laboratory Research Background
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
A ball and stick model of a molecule of Human Glucagon, a hormone produced in the pancreas and used by the body to raise levels of glucose in the blood. Glucagon worksin the opposite manner to Insulin, which lowers levels of glucose in the blood - together they work to keep glucose levels stable.
PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
Human had writing word endorphins and chemical formula. Endorphins are among the brain chemicals known as neurotransmitters, which function to transmit electrical signals within the nervous system

molecular model of Sovaldi (generic name: Sofosbuvir), the most popular drug to treat hepatitis C infection
Remdesivir is a broad-spectrum antiviral medication, it is a specific treatment for COVID-19. 3d illustration
Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, which was professionally checked. Color symbols - light blue=carbon, red=oxygen, blue=nitrogen, white=hydrogen, green=phosphorus
Camostat drug molecule. Serine protease inhibitor, investigated for treatment of Covid-19. 3D rendering. Atoms are represented as spheres with convent
A ball and stick model of a molecule of gamma-Cyclodextrin. Composed of eight glucose sugar molecules bound into a ring structure, cyclodextrins are easily made from simple starch. The large ring can bind smaller molecules within it, making Cylodextrins useful in drug-delivery applications and also to clean up toxins (such as heavy metals) in the environment. Currently, gamma-Cyclodextrin is being considered as a structure which can bind to and hold carbon dioxide gas for carbon capture and storage as a way to manage the effect of excess carbon dioxide on the climate.
